でアプリを入手しましたNavigationController。pushViewControllerおよびのアニメーション遷移スタイルを変更するにはどうすればよいpopToViewControllerですか？

UPD

@lawickoanswerのようなカテゴリを作成しました。しかし、関数を呼び出そうとするとエラーが発生しました

[self.navigationController pushViewController：places withCustomTransition：CustomViewAnimationTransitionPush subtype：CustomViewAnimationSubtypeFromLeft];

エラーは次のとおりです：「宣言されていない識別子の使用'CustomViewAnimationTransitionPush'」

この部分をどこで宣言する必要がありますか：

typedef enum {
    CustomViewAnimationTransitionNone,
    CustomViewAnimationTransitionFlipFromLeft,
    CustomViewAnimationTransitionFlipFromRight,
    CustomViewAnimationTransitionCurlUp,
    CustomViewAnimationTransitionCurlDown,
    CustomViewAnimationTransitionFadeIn,
    CustomViewAnimationTransitionMoveIn,
    CustomViewAnimationTransitionPush,
    CustomViewAnimationTransitionReveal
} CustomViewAnimationTransition;

今書く私はそれを宣言しますUINavigationController+Additions.h

UPD 2：もう1つの新しいエラー：

Undefined symbols for architecture i386:
  "_OBJC_CLASS_$_CATransition", referenced from:
      objc-class-ref in UINavigationController+Additions.o
  "_kCATransition", referenced from:

すべての_kCATransitionsで同じエラーが発生する

UINavigationController私が作成したこのカテゴリをチェックしてください。ほぼすべての可能なトランジションでプッシュとポップを行うことができ、QuartzCore トランジションのサブタイプもサポートされているため、まさに必要なことを実行できます - 左からビューをプッシュします。次のようにします。

[self.navigationController pushViewController:[[MyController alloc] init] withCustomTransition:CustomViewAnimationTransitionPush subtype:CustomViewAnimationSubtypeFromLeft];

コードは以下です。ヘッダー部分に入れる必要がある最初の部分:

// IMPORTANT - basic transitions like flip and curl are local, they reside only in animation block. Core animations however,
// once assigned to the layer, stay until changed or reset (by assigning nil as layer animation property)

#import <Foundation/Foundation.h>
#import <UIKit/UIKit.h>
#import <QuartzCore/QuartzCore.h>

typedef enum {
    CustomViewAnimationTransitionNone,
    CustomViewAnimationTransitionFlipFromLeft,
    CustomViewAnimationTransitionFlipFromRight,
    CustomViewAnimationTransitionCurlUp,
    CustomViewAnimationTransitionCurlDown,
    CustomViewAnimationTransitionFadeIn,
    CustomViewAnimationTransitionMoveIn,
    CustomViewAnimationTransitionPush,
    CustomViewAnimationTransitionReveal
} CustomViewAnimationTransition;

#define CustomViewAnimationSubtypeFromRight kCATransitionFromRight
#define CustomViewAnimationSubtypeFromLeft kCATransitionFromLeft
#define CustomViewAnimationSubtypeFromTop kCATransitionFromTop
#define CustomViewAnimationSubtypeFromBottom kCATransitionFromBottom

@interface UINavigationController(Additions)

- (void)pushViewController:(UIViewController *)viewController withCustomTransition:(CustomViewAnimationTransition)transition subtype:(NSString*)subtype;

- (void)popViewControllerWithCustomTransition:(CustomViewAnimationTransition)transition subtype:(NSString*)subtype;
- (void)popToRootViewControllerWithCustomTransition:(CustomViewAnimationTransition)transition subtype:(NSString*)subtype;
- (void)popToViewController:(UIViewController *)viewController withCustomTransition:(CustomViewAnimationTransition)transition subtype:(NSString*)subtype;

@end

この 2 番目の部分は、実装ファイルに入れる必要があります。

QuartzCore.frameworkエラーを解決するには、ターゲットに追加する必要があり_OBJC_CLASS_$_CATransitionます。

私は最近、独自のトランジションの作成に取り組みました。これが私が作成した再利用可能なライブラリです。

そして、これがあなた自身の移行を行う方法について話している私のブログ投稿です。

基本的な考え方は非常に単純ですが、navigationControllerの（現在の）ビューのCALayerスナップショットを取得し、アニメーションなしでビューをプッシュ/ポップして、新しいビューのCALayerスナップショットを取得し、それらのレイヤーに独自のアニメーションを追加してから、アニメーションが完了したら、これらのレイヤーを削除します。
